Minor Work — South Carolina license requirements
01 The project
The starting point is the work itself — Minor Work in South Carolina. The job determines which trades are involved, and the trades determine which license classifications may be required.
No project components are seeded for this project — we do not invent component lists without evidence.
02 Jurisdiction
This project is evaluated for South Carolina — the two-track, three-threshold state. The CLB commercial track licenses general and mechanical contractors above $10,000 total cost of construction (S.C. Code § 40-11-30), through an entity qualified by a 70%-pass qualifying party, backed by the license group's net worth or a surety bond in lieu, renewed biennially. The RBC residential track licenses a residential builder above $5,000 (≤3 floors, ≤16 units) and issues residential specialty credentials above $500 — a licence after exam for plumbers/electricians/HVAC, a no-exam registration for the rest. South Carolina jurisdiction page.
www.llr.sc.gov returned a 20-second timeout to this project's fetcher and to a real browser render, so the CLB and RBC fee figures, the 10/31 renewal dates and the residential bond amounts were surfaced from Google's index of those official URLs rather than machine-read (flagged reported). The statute behind every threshold and classification was read in full from scstatehouse.gov. Permit fees, local construction rules and any municipal business-licence rate were not researched and remain LOCAL_AUTHORITY_REQUIRED. The residential/commercial overlap on buildings is CONFLICT-SC-001, resolved by scope with both statements published side by side. State requirements are not the complete story for any locality.
03 Trade → license
Relations below are recorded per state — only this jurisdiction's classifications are shown.
Trades involved: no seeded components — trade resolution follows from the classification relations below.
- May require RES-SPECIALTY-REGISTRATION — Residential Specialty Contractor — Registration (RBC, no exam) confirmed S-SC-40-59 rule SC-RBC-SPECIALTYA small residential trade job (siding, drywall, a repair) over $500 needs only the NO-EXAM residential specialty REGISTRATION (§ 40-59-20(7)) — the LOWEST South Carolina threshold (rule SC-RBC-SPECIALTY).
- Component basis RESIDENTIAL-BUILDER — Residential Builder License / RBB (RBC) confirmed S-SC-40-59 rule SC-RBC-BUILDERIf the small job is part of constructing/superintending a residential building over $5,000 (≤3 floors, ≤16 units), the RESIDENTIAL BUILDER licence applies instead of a bare specialty registration (rule SC-RBC-BUILDER).
- Alternative path GC-BUILDING — General Contractors — Building (CLB) confirmed S-SC-40-11 rule SC-CLB-THRESHOLDA COMMERCIAL job at or under $10,000 needs NO CLB licence (§ 40-11-30 bites only above $10,000); over $10,000 it switches to the commercial General/Mechanical track (rule SC-CLB-THRESHOLD).
04 Scope
What the official sources say about the work involved — typed assertions, never a boolean "covers". Interpretations are marked as such.
- Officially included GC-BUILDING Commercial Construction Over 10000 (may_perform) S.C. Code Ann. § 40-11-30 S-SC-40-11 The commercial GC licence is triggered by TOTAL COST > $10,000 (rule SC-CLB-THRESHOLD).
- Officially excluded GC-BUILDING No Clb Licence Required At Or Under 10000 (may_not_perform) S.C. Code Ann. § 40-11-30 S-SC-40-11 Small commercial jobs fall BELOW the CLB trigger (no state licence needed), though a municipal permit may still apply (C_not_determined locally).
- Officially included RESIDENTIAL-BUILDER Residential Building Under 3 Floors 16 Units Over 5000 (may_perform) S.C. Code Ann. § 40-59-20(6) S-SC-40-59 The residential builder's licensed envelope (rule SC-RBC-BUILDER).
- Officially excluded RES-SPECIALTY-REGISTRATION Construct Additions Without Residential Builder Supervision (may_not_perform) S.C. Code Ann. § 40-59-20(7) S-SC-40-59 The home-addition boundary: a specialty tradesperson doing an ADDITION needs a residential builder over them (rule SC-RBC-ADDITION).
- Officially included RES-SPECIALTY-REGISTRATION Residential Solar Panel Installation By Registration (may_perform) S.C. Code Ann. § 40-59-20(7) S-SC-40-59 Residential solar rides the NO-EXAM specialty registration — again no standalone solar credential (rule SC-NO-SOLAR).
- Officially included RESIDENTIAL-BUILDER Any Residential Specialty Area Without Separate Credential (may_perform) S.C. Code Ann. § 40-59-20(7) S-SC-40-59 The umbrella rule — an exam-licensed residential builder subsumes the specialty areas (rule SC-RBC-BUILDER-SCOPE).
